数据只有10个observations，分三个固定时期收集，14 items，变量是28个，每个item
有或无（0，1）和item's amount. 大部分是0，请问可以用Longitudinal Data
Analysis? | i*****y
发帖数: 188 | 2 looks like you have binary data collected over time?
what do you mean by 14 items and 28 variables? | G**7

Yes, binary outcome, have item( value as 1) or no item(value as 0), if have
item, then the amount is no-zero, so 14 items, each has item and item_amount
, so total 28 variables. Most of them are zero.
collected data three times every other week. one of data as following:
ID item1 item1_amount item2 item2_amount ........item14 item14_amount
001 1 5 0 0 0 0
002 0 0 0 0 1 21

010 1 2 1 8 0 0

but your question is a little confusing
10 obs is ok. but there is no time variable here, what do you mean by
longitudinal? |
